ORGANIC-INORGANIC SEALANT FOR INTERNAL AND EXTERNAL PROTECTION OF PHOTOVOLTAIC CELL

摘要

PURPOSE: An organic-inorganic sealant for internal and external protection of a dye-sensitized solar cell is provided to prevent inflow of electrolyte of external impurities while preventing external leakage of electrolyte. CONSTITUTION: An organic-inorganic sealant for internal and external protection of a dye-sensitized solar cell is formed by a step of forming nonsolvent silica sol by substituting a functional organic monomer or a silicon compound for an organic solvent which is included in an organic solvent-replacing silica sol formed by replacing solvent in silica sol of which surface is modified by functional alkoxy silane; and a step of adding a reaction initiator and an epoxy resin, which is an organic polymer, to the nonsolvent silica sol.
